Adding a chardev backend for spice, where spice determines what to do with it based on the name attribute given during chardev creation. For usage by spice vdagent in conjunction with a properly named virtio-serial device, and future smartcard channel usage. Example usage: qemu -device virtio-serial -chardev spicevmc,name=vdagent,id=vdagent \ -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 v4->v5: * add tracing events * fix missing comma * fix help string to show debug is optional v3->v4: * updated commit message v1->v3 changes: (v2 had a wrong commit message) * removed spice-qemu-char.h, folded into ui/qemu-spice.h * removed dead IOCTL code * removed comment * removed ifdef CONFIG_SPICE from qemu-config.c and qemu-options.hx help.

# Trace events for debugging and performance instrumentation
|
|
#
|
|
# This file is processed by the tracetool script during the build.
|
|
#
|
|
# To add a new trace event:
|
|
#
|
|
# 1. Choose a name for the trace event. Declare its arguments and format
|
|
# string.
|
|
#
|
|
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
|
|
# trace_multiwrite_cb(). The source file must #include "trace.h".
|
|
#
|
|
# Format of a trace event:
|
|
#
|
|
# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
|
|
#
|
|
# Example: qemu_malloc(size_t size) "size %zu"
|
|
#
|
|
# The "disable" keyword will build without the trace event.
|
|
# In case of 'simple' trace backend, it will allow the trace event to be
|
|
# compiled, but this would be turned off by default. It can be toggled on via
|
|
# the monitor.
|
|
#
|
|
# The <name> must be a valid as a C function name.
|
|
#
|
|
# Types should be standard C types. Use void * for pointers because the trace
|
|
# system may not have the necessary headers included.
|
|
#
|
|
# The <format-string> should be a sprintf()-compatible format string.
